PlNCH-BAR FOR MOVING CARS.

SPECIFICATION forming part of Letters Patent No. 309,864, dated December30, 1884.

Application filed September 16, 1884. (No model.)

To all whom it may concern.-

Be it known that we, JOHN MOORE and ARTHUR J. OLEARY, citizens of theUnited States of America, residing at Chicago, in the county of Cook andState of Illinois, have invented certain new and useful Improvements inPinch-Bars for Moving Cars, of which the following is a specification,reference being had therein to the accompanying drawings.

Our invention relates to an improved pinchbar for moving cars.

In handling cars, especially freight-cars, during the unloading thereof,it is often found necessary to move them a short distance, and for thatpurpose a suitably-constructed bar is inserted between the car-wheel andthe track, and the wheel forced to partly revolve by applying pressureto the handle end of the bar.

The object of this invention is to improve the general construction ofsuchinstruments, and thereby gain in their construction strength,durability, and effectiveness; and to the accomplishment of that end theinvention con-. sists of certain novel devices and combination ofdevices, as will be described and claimed.

.Reference will be made to the accompanying drawings, in which Figure lis a side elevation of a car-wheel showing the pinch-bar in positionready for use. Fig. 2 is a plan view of the pinch-bar 011 an enlargedscale and with the handle broken away, and Fig. 3 a sectional view ofthe parts shown in Fig. 2.

Like letters refer to like parts in each view.

A represents a car-wheel, and B a section of track upon which it ismounted. The pinch-bar consists of a head, 0, and handle D, the partsheld together in any suitable manner, but preferably by forming a socketin one end of head 0 and inserting the handle into the same. Handle Dmay be formed of any suitable material; but we prefer the constructionand arrangement shown in Fig. 3. As there represented, the handleconsists of a pipe screw-threaded upon one end and inserted into asocket screw-threaded for a certain distance upon its inner face andcountersunk from the end of the thread to the outer end of the head. Inthis manner we avoid threading the handle at that point where it is snbjected to the greatest strain, and thereby add to its strength anddurability. The head 0 may be formed of any material sufficiently hardto withstand the strain to which it is subjected, and said head ispreferably of the shape shown, to have it more perfectly conform to theshape of the wheel and track between which it is inserted. Verticallythrough head 0 there is formed an opening through which a plate, E, ispassed. The plate, which is preferably formed of steel, is of such alength that when in position it will protrude a short distance from eachside of the head. Each end of plate E is pointed, and its position inthe head can therefore be reversed when one end has worn away. Upon itsfront face it is provided with a series of semicircular notches, a,adapted to receive a pin, 1), said pin being passed through a suitableopening formed transversely through head 0: By this construction it willbe seen that plate E is firmly held in position in the head by pin b,and by providing it with a numberof the notches a its position may bevaried.

In using our pinch-bar the forward pointed end of head C is placedbetween the track and the wheel, the lower end of plate E resting uponthe track and serving as a bearing. The handle is then raised anddepressed, and pressure thereby applied against the wheel and it causedto revolve, as will be understood.

\Vhat we claim is- 1. Apinch-bar consisting of a head, a handle securedto the head, and a plate passed vertically through the head, as setforth.

2. A pinch-bar consisting of ahead, a handle secured to the head, and aplate pointed at both ends and passed vertically through the head, asset forth.

3. A pinch-bar consisting of a head, ahandle secured to the head, and aplate passed vertically through the head and held removably therein, asset forth.

4. A pinch-bar consisting of a head, ahandle secured to the head, and aplate passed vertically through the head, the plate adjustably andremovably mounted in the head, In testimony whereof we aflix oursignatures as set forth. in presence of two witnesses. 5. In a pinch-barthe combination, with JOHN y 1 MOORE. socketed head 0, of handle D andplate 1y, ARTHUR ULEARY 5 the parts arranged as described and shown.

6. The combination, with head 0 and its \Vitnesses: handle, of plate Eand pin 1), plate E formed M. J. GLAGETT, with notches a, as-set forth.LOUIS NOLTING.
